We’ve noticed we don’t find monarch caterpillars on milkweed plants that have ants on them. We’ve also noticed if ants start coming on a plant with a caterpillar on it, the caterpillar disappears. It doesn’t seem to show up on a neighboring milkweed plant either.

I’m wondering if anyone has a way they keep ants off these plants so the caterpillars can continue their life cycle in peace.

The caterpillars might wander if food is low on the plant or when they want to make a chrysalis they often crawl off the plant.

Are your plants in the ground or in pots? Just curious cause I’ve had aphid problems across all of mine but never ants since I grow mine solely in pots.

Why native plants?

According to the The National Audubon Society:

Restoring native plant habitat is vital to preserving biodiversity. By creating a native plant garden, each patch of habitat becomes part of a collective effort to nurture and sustain the living landscape for birds and other animals.
